ViiV Healthcare's Breakthrough Findings on HIV Treatment

ViiV Healthcare Unveils Promising Study Results for HIV Treatment
ViiV Healthcare has reported remarkable findings regarding the management of HIV through their recent EMBRACE phase 2b study. This new research highlights the efficacy of specific treatments designed to suppress viral levels in adults already under HIV treatment.
Key Findings from EMBRACE Phase 2b Study
The EMBRACE study focused on the combination of N6LS (also known as VH3810109 or VH109) administered every four months alongside monthly cabotegravir long-acting (CAB LA). This innovative approach maintained viral suppression in participants who were already stabilized on other treatment regimens.
Statistical Insights from the Study
Insights from the six-month primary endpoint measure revealed significant findings:
- A remarkable 96% of individuals who received VH109 at 60mg/kg via intravenous (IV) administration, compared to 88% of those who received 3000mg subcutaneously (SC), managed to maintain their HIV-1 RNA levels below the threshold of 50 copies/mL.
- From the results, only 4% of participants in the IV group and 6% in the SC group recorded HIV-1 RNA levels of 50 copies/mL or higher by the six-month mark. In contrast, none of the participants in the standard-of-care group experienced a rise in viral levels.
- Both administration methods of VH109 demonstrated good tolerability overall, albeit with a higher rate of infusion site reactions noted in the SC group (14%) compared to none in the IV group.
- ViiV Healthcare anticipates continuing developments with a six-month IV formulation of VH109 as part of their ongoing EMBRACE part two trial.
Exploring Investigational Antiretroviral Therapies
In addition to the EMBRACE results, ViiV Healthcare shared findings from two phase 2a proof-of-concept trials centered around its investigational antiretroviral therapies, including VH4524184 (VH184) and VH4011499 (VH499).
Performance of VH184 and Its Impact
VH184 exhibited impressive potency across all dosages during the study period. Notably, after a ten-day monotherapy, substantial decreases in viral loads were registered across various doses, with the highest reduction of -2.69 log10 recorded with the 300mg dosage. Importantly, no mutations that confer resistance to the drug were detected.
Insights into VH499 Trials
Furthermore, the trials investigating VH499 demonstrated that all oral doses (25mg, 100mg, and 250mg) successfully reduced HIV-1 viral loads, ranging from -2.2 log10 copies/mL in the 250mg group to -1.8 log10 copies/mL for the 25mg and 100mg groups. VH499 was well tolerated, with mild to moderate adverse events, and no participants withdrew due to adverse reactions.
Future Directions for ViiV Healthcare and Shareholder Collaboration
ViiV Healthcare, primarily owned by GSK Plc (NYSE: GSK), continues to focus on developing effective treatment options for HIV. With partners such as Pfizer Inc (NYSE: PFE) and Shionogi, ViiV leverages collaboration to advance therapeutic innovations and improve patient outcomes.
Look Forward to Upcoming Developments
This positive momentum is expected to continue as ViiV Healthcare prepares for more in-depth studies and evaluations of their investigational therapies. Their commitment to enhancing treatment paradigms reflects ongoing efforts to revolutionize HIV management.
